...The Physics of a Bow and Arrow A bow and arrow operates on certain principle of physics. I will be investigating what factors affect the accuracy of a bow and arrow. Figure 1 - The change in the shape of the bow as the archer draws it. Figure 1 - The change in the shape of the bow as the archer draws it. A bow is a basic machine called a “two-arm spring”. Energy is stored when the archer bends the bow. It may look like the string is being stretched, however, it is not stretched but the shape of the bow is changed. The stored energy is then transferred to the arrow in the form of kinetic energy. The greater the draw length, the greater the momentum and energy that the arrow gains. A longer draw length will influence your accuracy. You, as an individual, need to find the draw length that you are most comfortable with. With your own unique draw length you need to have an anchor point. This point is the place where your hand will be every time you shoot an arrow. This will greatly improve the accuracy of the shot. Figure 2 - Correct form to shoot an arrow Figure 2 - Correct form to shoot an arrow In archery your form is very important. If you do not have the correct form then you will not be able to shoot properly and you might hurt yourself. In Figure 2 (left) we can see the correct form when shooting an arrow. Old military snipers used a technique they called B.R.A.S. Breathe. If you are do not breathe then you will not be able to focus clearly on where you are...

...Trajectory of a Bow and Arrow Bows and arrows have a great deal of variance to them. From the type of bow you use, the material, the bowstring, the wind, and where you’re shooting from, many different things could happen. Cool guy is in an archery competition and he is about to take his first shot. Cool guy releases the arrow from a height of 3 feet and it hits its highest point (5 feet) when the arrow is 50 feet from where it was released. The target is 120 feet away and the center of the bulls eye is exactly 3 feet above the ground, and 4 inches in diameter. Assuming that Cool guy shoots a perfectly straight shot, will he hit a bulls eye? We need to use the vertex form of the equation y = a(x – h)^2 + k To find the vertical height of the arrow as it approaches the target. Since the arrow has a maximum height of 5feet when it has traveled 50 feet toward the target, we know that the vertex is at (50, 5). Substituting this into the equation, we get: y = a(x – 50)^2 + 5 To find the stretching factor, a, we need to plug in a point other than the vertex. Since the arrow was initially launched at a height of 3 feet, the parabola goes through the point (0,3). Replacing x and y in the equation, we get: 3 = a(0 – 50)^2 + 5 3 = 2500a + 5 -2 = 2500a a = -0.0008 This gives a final equation of y = -0.0008(x – 50)^2 + 5 We can find the height of the arrow when it hits the target by plugging in 120 feet in for x. y = -0.0008(120 – 50)^2 + 5 y = 4.888 feet The bulls...

...May 4, 2015 His 101-001 The History of the Bow and Arrow in Early Western Civilization Early prehistoric humans hunted with ancient spears. The bow and arrow is one of man’s most ancient technologies in prehistoric hunting and war weaponry. The development of the bow and arrow allowed early western civilization to evolve by providing a more effective weapon than the spear, which was used for hunting, protection, and war. Stone Age humans were the first to use the bow and arrow, in which there is no argument this ancient weapon helped save many lives by providing safety during hunting and war. Spears were used for hunting and protection prior to the invention of the bow and arrow. The arrow, essentially is a specialized...

...to kill you, you can’t afford to trust anyone. Or can you? That’s what sixteen-year-old Katniss Everdeen thinks when she volunteers for her twelve-year-old sister, Prim. Trust no one. Come back alive. Those are her only priorities. When Katniss enters the arena, her original plan is to run, run, run as fast as she possibly can away from the Cornucopia-- A giant, gleaming dome filled with weapons, food, water, and other supplies. She doesn’t want to enter the bloodbath-- The beginning of the Games so nicknamed because of brutal battles that take place over the supplies the Cornucopia holds. One item changes everything, though: A gleaming bow. Her ideal weapon. The bow... It could buy her food and defense. It could be the very key to her survival. And, after all, how hard can it be to get one bow? Apparently, very. After all is said and done, Katniss ends up in a tree for the night, exhausted and weaponless. She was only able to acquire a backpack containing a sleeping bag, a bit of food, and an empty water canteen. After hardships such as tracker jackers (deadly insects similar to hornets or wasps), a forest fire, and her only ally dying, the Game-makers make an announcement: If two tributes are from the same District, they can both win. Katniss immediately thinks of Peeta, even though it’s obviously something from the Capitol directed at the two specifically, being the “star-crossed lovers” of the Games....

...03-01-15, 05:57 AM#1 Prologue For years people have dreamed of Virtual reality ranging from video games to entire worlds. There have been numerous amounts of stories and speculation for as long as the idea has existed. But now with technologies growing and improving every day the dream of virtual reality has become a reality with the new release of a Virtual Reality game called Mythical Legends with many flocking to get their hands on it. With wild speculation, stories and dreams over the year people expecting great things. Mythical Legends has had great hype across all forms of media, and for good reasons. First the game is running on a new system that incorporates not just the Game Masters; GM’s for short, but also the creation of multiple advanced artificial intelligences that support’s the virtual world and create new events and areas as the game progresses. Besides that another amazing feat is that the NPCs and Mobs of the game cannot be easily told apart from any other players. The Beta testers where surprised and overwhelmed by the games realism and by its gameplay. They played throughout a number of regions on the continent of Tellus starting at one of the four kingdomsRedstone, Thorcyn, Thlyiss, and Andesit. Each kingdom home to the four core races of Humans, Elves, Halflings, and Dwarves. After the six month testing time the programmer of the game accelerated the game’s time over a 1000 years in game time adding more history and lore. With the games...

...are turning eighteen. Why not give them a homemade corsage? To make them feel even more special. How? Listen for the next few minutes and you will learn how to make this 10-step DIY or do it yourself wrist corsage. For the corsage, you’re going to need some simple basic DIY ingredients like stapler, glue gun with the glue stick, and fabric ribbon for about 12” by 1.5” for your bow. You’ll also need a beaded bracelet or any decorative bracelet where you can attach your final corsage. Finally, you need to add some decorative flowers and leaves. I think the cutest flowers for a corsage are mini-roses, paperwhites, cherry flowers or any artificial flowers of your own choice. Now that we have our materials before us, we’re going to start by gluing the fabric ribbon together at the ends to have a loop and staple it at the center to make a two-point bow. Do this with the other ribbon in a like manner. Attach the bow at the top of the other in an opposite direction to make a four-point bow. The next step we’re going to do is to take at least three pieces of any artificial leaves and glue them above the bow in a triangular distribution. Now, it’s time to begin adding in with your flowers. Since the roses take up the most space, I’ll add those first by stripping off the leaves and glue them at the top. (Whenever I gave flowers to my grandma, I always give her white roses because white roses are often used as an expression of remembrance.)After the roses are...

...maiden upon the land. The people worshiped them because they were rich beyond anyone’s imagination. One day Alex and King Matilor took the carriage to town for some goods. Alex spotted a brand new bow and arrow that he wanted very much. He asked his dad “Please father can I have it, please.” His father repeatedly told him “NO”. Alex then threatened to run away where no one could find him, so his father gave in a bought him the bow and arrow. They finished their errands and headed back home. Queen Matilor warned Alex that he could only play with the bow and arrow outside where no one was around and only shoot at the target board. He had to wear his armor while outside at all times. Alex was in love with his new bow and arrow and he played outside all day, even breaking his mother’s rules and shooting at the harmless birds. As the sun went down, Queen Matilor called out for Alex to come in for supper. He begged, “just a little longer mother, please.” She replied, “No, You’ve been out all day long and it’s time for you to eat supper.” He groaned as he went upstairs to wash up. Waiting for everyone to fall asleep, Alex anxiously lied in his bed staring at his bow and arrow for the next opportunity to play with it. After an hour or so, Alex creped down the hall with his bow and arrow, to his parents room to see if they were sleeping. When the coast was clear, Alex pretended he was a warrior and shot at the Knight in armor across the hall. The arrow ricochets and hit Alex...

...reach their peak performance. From knowing elbow and bow arm angles to the calculating the Draw Weight, these uses of geometry are crucial to ensuring the arrow will land center of the target. Because most archery tournaments take place in the outdoors to replicate the history of the sport, there are several independent variables that the archer cannot control. But to ensure that the archer can control all other manipulatable variables, it is crucial that they understand basic geometric angles along with a key formula to ensure that they will achieve the ultimate goal of the arrow reaching the ten-point ring. According to M. Schottenbauer,...

...hopes of reaching a lifeboat. The ship's stern slowly rose into the air, and everything unsecured crashed towards the water. While the stern rose, the electrical system finally failed and the lights went out. Shortly afterwards, the stress on the hull caused Titanic to break apart between the last two funnels, and the bow went completely under. The stern righted itself slightly and then rose vertically. After a few moments, at 02:20, this too sank into the ocean. Only two of the 18 launched lifeboats rescued people after the ship sank. Lifeboat 4 was close by and picked up five people, two of whom later died. Close to an hour later, lifeboat 14 went back and rescued four people, one of whom died afterwards. Other people managed to climb onto the lifeboats that floated off the deck. There were some arguments in some of the other lifeboats about going back, but many survivors were afraid of being swamped by people trying to climb into the lifeboat or being pulled down by the suction from the sinking Titanic, though it turned out that there had been very little suction. As the ship fell into the depths, the two sections behaved very differently. The streamlined bow planed off approximately 2,000 feet (609 m) below the surface and slowed somewhat, landing relatively gently. The stern plunged violently to the ocean floor, the hull being torn apart along the way...

...another year to go before I slide into the 40s. The forties; I’m not even sure what happened to the thirties, and already I have to learn to write a new digit. In those quiet moments of the morning when introspection is possible, I have been able to confirm that I remain as spirited, indomitable, adventurous, exciting and curious as I was when I was 18. So I figure that in order to avalanche through the forties, health is going to be an incredibly important attribute in my existential makeup. My knees creak when I walk down the stairs. They ache when they stay bent for longer than 10 minutes. My left shoulder is recalcitrant on the good days, and frozen stiff exactly when I need it most. I have never played tennis before, nor used a bow and arrow. So how on Earth did I get a left tennis elbow and a right archer’s elbow? It appears that I have fallen into a terrible trap. I believe the old saying goes something like, “you won’t know you miss it till after it’s gone”. My health; my vigour. I am losing it. But I still love the great outdoors! I like to kayak. I like to run in the rain; skip rope. Let my whole shoulder drop off when I am paddling. Never mind, it’ll be worth it. But in all my times doing what I love most, one annoying event keeps taking place that mars the experience. My lungs. Oh, my god-forsaken lungs. They burn!! Before my legs can fail me, before my paddling arms can paddle no more, my lungs raise the white flag first. I strain my diaphragms as hard as...

...McDonald’s Canada aims to humanize image with new ad campaign For more than two years, McDonald’s Canada has given consumers a behind-the-scenes look at the company, including how its meat is processed, and how burgers are Photoshopped for ads. It’s an attempt to change misconceptions about the fast-food giant. Now, the company is shifting to a more emotional approach in its marketing. For a new advertising campaign, which launched on Monday evening, a small film crew criss-crossed the country interviewing more than 450 McDonald’s customers, staff, and suppliers. Some of those people will be the face of the “Welcome to McDonald’s” campaign. It will include TV ads featuring candid shots captured on the tour, and billboards and posters featuring photographs of real people, listing their hometowns and quotes about why they came to their local restaurant. Online and on social media, the company will post 30 videos telling short stories about some of those people. It is hoping to encourage more people to share their stories, to add to those videos. “[Consumers] still think of it as a global brand, and they don’t recognize the rich history we have in Canada,” said Antoinette Benoit, senior vice-president of marketing for McDonald’s Canada. “That’s what this work is about. It’s about showing the human side of the brand.” It’s a connection with customers the company is fighting to maintain. In January, McDonald’s Corp. announced that its net income fell 21 per cent last quarter...

...Edward LeBar November 25th, 2009 HIST 017 Prof: Dan Hambly History of Warfare: Essay Assignment The two key individual advancements of weaponry in warfare that I believe were most relevant to the change in warfare tactics were the Spears used by the Ancient Greek and Macedonian Phalanx (300 B.C.E) and the Long Bow used by the British (1300-1500 AD). Each of these weapons made a huge impact in warfare upon being developed and changed the course of history of their armies who wielded these weapons of excellence. Each weapon was wielded by soldiers slaying millions of people during many glorious historical battles still taught to students around the globe today about their importance to warfare. “One of the earliest, and certainly the deadliest of these first purpose-made weapons, was the spear” (Weir, 2005). The spear was developed in early known warfare, and had an impact when the Ancient Greeks wielded the spear in their battles. The Spear was a simple weapon to make as it consisted of a wooden poll 6 to 8 feet in length with a sharp piercing arrowhead attached to the end capable of puncturing any enemy armor. The Ancient Greek’s developed the spear to be able to attack an enemy from a longer range than the sword and used the spear with tactics and coordination with a Hoplon shield protecting the Hoplite soldier which was later called a Phalanx. The spear proved to be very useful to the Greek Phalanx providing the Greek’s with many victories with this particular weapon...

...BowFishing Equipment The sport of bowfishing has, perhaps, evolved more rapidly during the past few decades than any other sport that has existed for that long a period of time. A few decades back, ordinary bows were used for this sport, and regular arrows were fitted with lines for fish retrieval. Needless to say, this put bowfishermen at some risk of injury or even, occasionally, death from arrow snapback as the line became tangled in the bowstring. Most bowfishing was carried out from shore, and there was little specialized equipment for the bowfisherman to use. Huge changes have come over the sport of bowfishing, however, largely because of immense and useful advances in the gear and equipment that can be used during the course of the hunt. The use of boats and fishing platforms have made bowfishing more engaging and exciting, with boat-based bowfishing being the most dynamic and interesting type for many fishermen....
